Infidelity is always painful for the betrayed. But when there’s a baby on the way, it makes the sting that much worse. It’s cheating for two!

Unfortunately, it is not at all uncommon for husbands to stray from their pregnant partners – and not just in Hollywood. According to psychologist Robert Rodriguez, 10% of fathers-to-be cheat on their baby mamas.

What would drive a man to commit such egregious treachery? Some men blame their adultery on a feeling of being usurped by the baby. Others say they were looking for an escape from the stress of impending fatherhood. A few men admit they felt repulsed by their partner’s changing physique or were turned off by the idea of their baby being “involved” in their intimacy. Occasionally, the pregnancy was poorly timed, as the relationship was already as good as over.

Ashley Madison founder Noel Biderman posits that in many cases, it’s simply a matter of the pregnancy having led to “a period of abstinence” for the couple. Then there are those men that are going to cheat no matter the circumstances. Their wife’s pregnancy is incidental.

Whatever their reasons, none of the celebrities on this list are going to win Husband of the Year.

It’s not easy being a single mother. And it’s arguably harder still to be a famous single mother. Of course, it’s not just Hollywood that shares the mentality that pregnant women and babies are fair game for public scrutiny.

It’s no wonder that some celebrities want to keep the public out of their family affairs. In 2018, the nuclear family is a myth. A baby doesn’t need one parent of each gender to have a happy, healthy upbringing. But that doesn’t stop inquiring minds from prying. When a romantically unattached star announces they are pregnant, the people must know who else was involved. And sometimes, these mothers-to-be quite rightly don’t feel like sharing.

The women (and 2 men) on this list made a choice to keep the particulars of their conception private. Some of them were successful in their attempts. Others were legally forced to spill the beans or it came out after a romantic reconciliation. In some cases, paternity is all but public record. A few women just got tired of fending off the question. Whatever the case, even celebrities have a right to raise their children however they see fit.
